<p>A flying disc (1) includes a night plate (2) of flexible material and an inflatable chamber which is preferably formed by the flight plate itself. The inflatable chamber suitably includes a valve (3) so that the degree of inflation can be varied by the user to alter flight behaviour. Where the flight plate (2) itself includes the inflatable chamber an annular lip (5) depends from the periphery of the night plate for increasing flotability by entrapping air in flight. </p> |
